It is not a secret that my short interaction with Murat and
my observation the progress he has with his playback made me to feel that his
is an idiot. There is nothing new in it, most of accidental audio people are
idiots. Nevertheless, I think it...

Besides hornresp modeling, is there things to think about when starting design and build of midbass channel from scratch? The range I need is 60 to 300 hz. It will be used with 6db/octave crossover. It will be located under my midrange horn -- the mo...

Tubebuilder, I am not sure what you are trying to do. According to the “Romy’s Rules” (whatever it means) people do not build Midbass horns but they build an installation that might include the Mid Bass horns. You do not need to choose a project jus...

I find an interring house that I like. Ironically it is very much not what I was looking audio-wise. It has a lot of real-estate lucidness and I feel it has a lot of very interesting audio opportunities. The listening room is small, 2 times small...

I do not do anything with my Opera Room, and I am not sure if I will. Still, from time to time I pick from the tree of possibilities some very kinky fruits. My love to Mussurgsky is know and last weekend I visited my local audio guy who has a very go...

Both UB Horn roll off circa 130Hz in room. There are a couple of rough MDF boxes here that I knocked up from spare sheet a while back. Have not tested them specifically at the intended spot behind me but running around with a microphone shows those...

[quote user="Wojtek"]You mentioned it yourself that the most interesting midbass you ever heard was from corner horns. Why not utilize if you can a pair of K-horns (or clones) bass (midbass really) bins with sort of moveable fake corners? They can be...

Since my left channel along with midbass horn is more or less configured I made today a first rest of the full assembly - with LF section. The midbass does somewhere hear 40Hz and I set the LF section for 34Hz, drove it from B2 via the SMS crossover....

To me the big green drivers in the midbass horn look like old Siemens Klangfilm or Telefunken (or other German manufacturer) 10 inch units. Maybe 12 inch... I had a pair of 8 inch Klangfilm once and they do have interesting tone across a couple of oc...

I need to say that for whatever reasons the midbass horns acts as a phenomenal tranquilizing sedative to listen some older recordings. The midbass horns make bad sound much more palatable and make attention to be much less distracted to quality of ...

From the time of the insertion and setting the proper crossover my midbass is growing and growing, getting larger, deeper and better in all aspects. I am not kidding and now, when I have no ULF channels operational, it is very obvious. I can’t explai...

[quote user="Romy the Cat"]Last night Levine and BSO played a phenomenal Mahler 5, truly great play. I had some issues with BSO sound and I probably will bring it up to them. Tonight I decided to listen the M5 broadcast for the first time and I ...

Murat,
I was looking at your midbass horn design and I am wondering, how are you planning to time align that long midbass with the rest of the channels that seem to be time aligned. I mean, currently the midbass is physically 4.3m behind all o...

[quote user="noviygera"]1. Let's say
the my original back chamber from the manufacturer is a good "starting
point". Is Romy saying that those last few hertz of the fine tuning of the
chamber volume are very important and audible, in other words th...

[quote user="Romy the Cat"]Of cause not but did you read and understand the Macondo
Axioms? The Macondo Axioms proclaims that an individual driver and individual channel
have to be set in maximum suitable for own topology operation. According to Go...

When you get a horn that will work i will trade for a couple weeks!I don't think wide band drivers are the ideal way to do things but the most cost effective way to injoy good sound i would like to make another pair to crossover from 3k to 10k.some...

[quote user="tuga"] I am curious as to how you'll "integrate" the 63Hz mode into your acoustic system but I can see it possible without any "room treatment". [/quote] Ric, what I need to know how my dedicated midbass section will be decaying. There i...

I thought that a digital crossover had a negative impact on sound quality -- especially for use between a midbass, midrange and tweeter channels. So I made an experiment a what I learned was not expected.I used my mid horn and two high pass filters i...

Having just returned from this show, I have a few comments on your comments... 1) Yes, it was the amp you posted the link to. 2) Yes, the tweeter and two MF channel drivers were GOTO 3) Your estimates on flare rates aren't too far off (don't kn...

If we are taking about multi-way horn-loaded acoustic system then in my view is it very important to plan the development in a specific order. Any deviations from the order are perfectly fine but they will affect cost/time/efforts of the project. Thi...

Great conductor but you never know what you get from him. I was listening tonight the FM recording from SymphonyShare of Dorati with CSO doing Mahler 6. Chicago Symphony play not well but whole together it is strangely powerful performance. As the pe...

[quote user="Rewind"]Macman: Maybe your tapped horns were too small. Speedysteve is absolutely in love with his, and you and him have a very similar setup with your 15" upper midbass horn and all.[/quote]Yes, Im sure you could make them better. I bel...

[quote user="noviygera"] Romy, I have somewhat
different possibilities than you are seeing. My system is physically higher
than most because my listening position is at standing height or sitting in a
high stool. I have used this litening height f...

because floor josts support and extend the walls (they are solid 2"x6")so just screwed the board tightly to them. Because I needed the boards only within 10' so I have 3 rows of 5' +5' with the seam in the middle. I cut the second layer of bards so ...

Do you have the speakers as pictured already in place, or at least in the form your beautiful rendering shows? I would recommend to try a mock up of this layout in your room and not proceed with the full custom build. For example, I don't think the a...

first post, hi everybody!plan to build a midbass horn around the gpa 515-8ghp, throat 9,9", mouth 24" x 39,37".945something sq inches.(excuse the strange numbers, metric units in europe)crossed at 500, s2 alu diaphr.(is it normal for the metals to ha...

It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE builds, but of the owner's design...

Jessie, looks nice. I never did it myself and can not appreciate the labor went into it. Horn-wise everything looks well- thought out. I personally would probably go for a monopod frame above the midbass horn (mergeing it in middle) as I feel it make...

Hi, Martin,
As I understand you are the AU guy who makes horns? I heard a lot about you, very welcome, it would be very interesting to hear your experienced…
I agree with you: what I say on the subject to be entirely true. :-) However, talking abou...

[quote user="MINGSU"]Most users use it for 200Hz down to 10 Hz above the horn cutoff frequency.[/quote]
Ming, I do not think you are “getting” what I am trying to say. OK, let to make bold statements: the people who use the 24Hz SG146LD4 drive...
